Dear CPMD users,

In the ATOM section, can the input coordiantes exceed the box dimension ?
For example, in a cubic box (10*10*10), a hydroxyl (-OH ) group has the
coordinates: Oxygen (0, 0, 9.5) and Hydrogen (0, 0, 10.5). Should I input
these coordinates or, Oxygen (0, 0 , 9.5) and Hydrogen (0, 0, 0.5) ? how
CPMD treats this  ?
Thanks.

BEST

XIANDONG
